Gegege no Kitarou (2007)

Born in a graveyard and raised by his father — who's literally just a sentient eyeball sitting on his shoulder — Kitarou is a yōkai boy caught between two worlds. Together with a scheming half-human rat man, a cat-girl who goes feral at the sight of fish (or danger), and a couple of ancient yōkai elders, Kitarou acts as a bridge between the human and supernatural worlds. When malevolent yōkai start causing trouble for humans, he steps in to sort things out, though the humans aren't always grateful and the yōkai aren't always wrong. This 2007 version from Toei Animation runs 100 episodes and adapts Shigeru Mizuki's classic manga with a darker, more comedic edge than you might expect from something with such a long legacy. Each episode draws from actual Japanese folklore, so you're basically getting a crash course in yōkai mythology wrapped in monster-of-the-week storytelling. The tone shifts between genuinely creepy horror moments and goofy comedy without it feeling jarring — think campfire ghost stories told by someone with good comedic timing. If you liked the folklore-driven atmosphere of Natsume's Book of Friends but want something with more bite, or if Mononoke's deep dive into Japanese spirits appealed to you but you're looking for something more episodic and accessible, this fits that space well. It's also a solid entry point if Yokai Watch got you curious about yōkai culture but you want the stories played a bit straighter and darker.
